Definitions

  • This invention pertains to an air bag restraint system for vehicles, and more particularly to a system with venting means to allow the air bag to collapse in a controlled manner.
  • Automobile collisions involve vehicle impacts that result in abrupt changes in the vehicle's velocity. Occupants riding within a vehicle must also sustain these velocity changes if they are to remain within the occupant compartment. However, the manner and timing in which they will experience them is dependent upon the way in which the occupant is restrained within the vehicle.
  • the occupant's velocity change equates to change in the magnitude of his kinetic energy.
  • the relationship between velocity and kinetic energy is strictly defined and given by well-known mathematical formulas.
  • the purpose of any occupant restraint system then is to help achieve this change in energy with a minimum of traumatic force.
  • the energy change is achieved by applying a restraining force over a given distance.
  • the less distance over which the force is applied the higher the applied force will have to be in order to achieve the given energy change.
  • the minimization of restraint force is therefore achieved by maximization of the "over ground" distance over which the force is applied.
  • the theoretical maximum over ground distance available to the occupant includes the following: the distance that the occupant compartment travels as the front end of the vehicle structure is deforming plus the distance within the compartment that the occupant can traverse before unwanted contact with a "hard” structural surface (i.e. steering wheel, windshield, instrument panel, etc.).
  • the over ground distance includes the crush of the vehicle's structure, it is important to begin restraining the occupant as soon into the crash event as possible. In this way, the occupant will be using the deformation of the vehicle to help dissipate his energy.
  • Air bag systems also involve a delay in the application of restraint load.
  • the sensing of the crash severity and decision to deploy in conjunction with the time required to deploy and fill the bag constitute the delay associated with inflatable restraint systems.
  • a restraint system As stated previously, the purpose of a restraint system is to minimize the traumatic force applied to achieve the occupant's required change in velocity . Strict minimization of the force magnitude is not sufficient in itself. The application of the force should be done in such a way as to minimize the trauma it incurs.
  • air bags excel over all other currently available restraint systems.
  • seat belts which essentially exert a line force across the pelvis and diagonally across the torso
  • an air bag distributes the restraint load over the entire upper torso and face.
  • the air bag's ability to spread the restraint force over a large area of the occupant's body significantly reduces the potential for trauma.
  • the air bag once the air bag is deployed, it becomes relatively rigid so that a secondary collision between the air bag and the occupant may occur which has a much lower impact then without the air bag, but may still be strong enough to cause injuries. In fact under certain conditions, the occupant may rebound hard enough to lose contact with the bag.
  • air bags have been suggested which have one or more relatively large vent holes for venting the gas from the air bag at a predetermined rate.
  • a clean gas i.e. a gas without particulate matter
  • the pressurized gas is preferably produced by reactions of chemicals because prior to the reactions, the solid and/or liquid reactants can be stored in a very small space. This consideration is especially important for air bags which are mounted in a steering column.
  • gas produced by such chemical means includes a large concentration of particulate matter and therefore it is unacceptable in air bags with venting holes described above because the vented gas escapes into the passenger compartment together with the particulate matter with detrimental effects on the occupants.
  • a further objective is to provide an air bag system with venting in which the pressurizing gas is produced by chemical reactions.
  • the inflator In order to apply restraining force as soon as possible, the inflator must quickly bring the bag pressure up to a significant level. As the occupant penetrates the bag thereby reducing the volume, the pressure rises further. In order to prevent the pressure, and thus the restraining force, from becoming too high, some of the gas is allowed to escape as the occupant in the present invention penetrates the bag. This is what is know as bag "venting".
  • the bag Without venting, the bag will essentially act like a spring, with the restraining force increasing proportionally with occupant penetration. For high penetrations, the force on the occupant will become unacceptably high along with the occupant rebound velocity away from the bag. By allowing some of the gas to escape during penetration, the pressure is held more constant, and the air bag becomes a much more efficient energy absorbing device. The rebound velocity, and its associated potential injuries are also significantly reduced.
  • the degree to which the bag is vented becomes a design parameter that considerably influences the system performance. Too much venting can result in the occupant over-penetrating the bag and impacting the steering wheel. Too little venting will cause excessive bag force and rebound velocities. Thus, the vent must be tuned to work with the bag, inflator, and other system components in order to obtain optimum performance.
  • the bag is made at least partially of a material which is gas permeable for allowing the gas to escape from the bag at a metered rated and at the same time to intercept and filter particulate matter generated during the production of the gas.
  • the gas generator may also be provided with a filtering means to localize the particulate matter around the gas generator.
  • FIG. 2 shows a plan view of an air bag used in the module of FIG. 1;
  • an inflator assembly 22 for generating a gas by chemical action.
  • the assembly comprises a metal ca 24 with exit holes 26. Holes 26 are preferably provided with a mesh 28.
  • a folded air bag assembly 30 Surrounding at least a portion of the housing, there is a folded air bag assembly 30. The assembly is secured to a support plate 32 by bolts 34 so that an air tight seal is formed by the bag around the holes 26.
  • Layer 42 is preferably made of a fabric which is permeable to air, such as for example, a fabric made by W. L. Gore and Associates, Inc under the name of GORE-TEX® Nanofabril Membrane.
  • This fabric is impermeable to water, but is permeable to gases and therefore is a good filtering material. It has been found that this fabric can filter out 99.9994% of the particulate matter having a diameter of 0.1 micrometers.
  • the inner component 44 is a support member strong enough to maintain the bag intact as it is pressurized.
  • This second component may be made for example of nylon, NOMEX®or other similar fabric.
  • Preferably component 44 is provided with a fireproof coating to protect the bag from combustion and heat during the inflation of the bag.
  • the air bag restraining device operates as follows.
  • an accelerometer (not shown) senses a crash it activates the inflator assembly 22.
  • gases are produced and expanded very rapidly, by combustion, or other chemical action. These gases exit through holes 26 and pressurize the bag assembly.
  • the bag assembly breaks out of the housing 10, by opening or breaking hub cover 16.
  • Some of the particulate materials which are the by-products of the combustion or other chemical action within the inflator assembly, are contained within can 24 by screen 28. Other particulate matter escapes into the bag assembly.
  • the occupant disposed between the bag and the motor vehicle seat is projected by the primary or secondary collision into the bag. The additional pressure within caused by the passenger's collision with the bag force gases to escape through the portion 49 of the upper section 36 bag.
